3. Instrument Inspection
Instruments are inspected before shipping and sent out in perfect condition.
Should damage to a device be visible, we recommend a thorough inspection of
the delivery packaging. In case of damage, please inform your parcel service /
forwarding agent immediately, since they are responsible for damages during
transit.
Scope of delivery:
The standard delivery includes:
• Compact Vortex Flow Meter
• Operating Instructions
model: DVZ
4. Regulation Use
Any use of the Compact Vortex flow meter, model: DVZ, which exceeds the
manufacturer’s specifications, may invalidate its warranty. Therefore, any
resulting damage is not the responsibility of the manufacturer. The user assumes
all risk for such usage.

5. Operating Principle
The compact KOBOLD Vortex flow meter, model DVZ, is used for measuring and
monitoring smaller and medium-sized flow of low viscosity, water-like fluids in
pipes.
The device works using the vortex process, making it virtually maintenance-free.
This involves the installation of a sharp-edged object (the vortex generator) in the
flow duct. A vortex is created behind the object whose frequency is proportional
to the flow velocity of the fluid.
The flow volume can be determined with a very great degree of accuracy by
measuring the vortex frequency. This achieves a very high linearity across the
whole measuring range.
The device can be fitted with switching, frequency or analogue outputs. There is
also an optional compact electronics package that includes a digital display, and
both a switching and analogue output.
6. Mechanical Connection
6.1 Check operating conditions:
• Flow rate
• max. operating pressure
• max. operating temperature
6.2 Installation
• Remove all packing materials and transport retainers and ensure that no such
materials remain in the device.
• Install with flow in direction of arrow
(universal mounting)
• Avoid pressure and radial tension
• Fasten the pipe at up stream and down
stream at a distance of 50 mm from the
connections
Attention! Retransfer the unit on
the metal bolting (not on the
plastic housing!) Mount switches
using the proper tightening
torque according the following
table!

Note! The switch may be damaged if it is tightened above the
tightening torque range. Also, if it is tightened below the tightening
torque range, the connecting thread section may loosen.
• Ensure inlet section of 10xDN and outlet section of 10xDN
• Avoid valves or large reduction on the inlet section (this increases the
inaccuracy of measurements)
• Check the seals of the connections
Attention! When used with an open output side, there is a danger of
cavitation.
7. Electrical Connection
7.1 General
Attention! Make sure that the voltage values of your system
correspond with the voltage values of the measuring unit.
• Make sure that the supply wires are de-energised.
• Connect the supply voltage and the output signal to the plug PIN’s as stated
below.
• We recommend the use of wires with cross sectional area of min. 0,25 mm².

9.5 Main menu items
9.5.1
Switching point
The switching point is entered in the menu item "Spo, SP1, SP2". A setting value
between 000 and 999 can be selected. This value can also include a decimal
point. The decimal point can be set at two points (e.g. 10.0 or 1.00). If the display
value exceeds the set switch point, the electronic is activated and is signalised by
a lightning LED.
If the hysteresis is equal to zero and the window point is de-activated, the
electronic switches back whenever the indicated value falls below the switching
point.
9.5.2
Hysteresis
After the setting of the switching point, the hysteresis can be entered as a
negative value in the "HYS" menu. The standard hysteresis value is zero. In
operation condition this can lead to ambiguous switching behaviour, if the reading
fluctuates around the switching point or window point. In this case, increasing the
hysteresis can put things right. The hysteresis relates to the switching point and
the window point (switching point minus hysteresis; window point plus
hysteresis).
Example: Switching point 100 l/min; Hysteresis: -2.5 l/min
The electronic switches when 100 l/min is exceeded and switches
back when the reading drops below 97.5 l/min.
9.5.3
Window point (duo-point)
As well as the switching point, it is also to define a "duo" (duo-point), the window
point. This must be higher than the switching point. By using the window point
and the switching point it is possible to monitor the measurement value in a
certain range. The switching point limits the measurement range to smaller
values and the window point to larger values.
page 14
DVZ K04/0810
DVZ
If the window point (duo-point) is less than or equal to the switching
point, an error report (Er4) will be indicated on the display and its
value is deleted and its function is invalid (in the case that the
window point and switching point out of adjustment).
The value is set in the same way as the switching point.
The window point is needed for process, in which monitoring of a certain
temperature range is necessary.
Example:
Switching point: 100 L/min; window point: 150 L/min;
hysteresis: -1 L/min
The electronic switches when 100 l/min is exceeded. If the switching value
remains between 99 L/min (100-1) and 151 L/min (150+1), the contact will also
remain in active switching condition (LED on). If it exceeds 151 l/min or is below
99 l/min the electronic switches back.
Switching behaviour
The following diagram clarifies the switching behaviour of the electronic switch.
The contact closes (contact type: no) when it drops below the switching point or
the window point. It only opens again if the window point plus hysteresis is
exceeded or if it drops below the switching point minus hysteresis. An LED
indicates the switching condition of the switching point.

9.5.4
Contact type
The function of the transistor switching output is set in menu item "Con, Co1 or
Co2". The switching function switches from
no - N/O contact to
nc - N/C to
Fr – frequency
(only Con and Co1)
and back.
N/O contact: contact closes when switching point is exceeded
N/C contact: contact opens when switching point is exceeded
Frequency: frequency output synchronised with the vane frequency
9.5.5
Current output
The current output is selected in menu items
"S-C" Start current indicated value < > 0(4) mA
"E-C" End current indicated value < > 20 mA
"SCS" Start current selection (0-20 mA or 4-20 mA).
The indicated value at which 0(4) mA flow is entered in menu item Start current.
The indicated value at which 20 mA flow is entered in menu item End current.
9.5.6
Change Code
The change code option "CCo" secures the unit against unauthorised tampering.
If the code is different from 000, the user must input the code immediately after
entering the adjustment mode.
10. Maintenance
The measurement device requires no maintenance if the measurement medium
does not cause deposits or include fibre parts, which wrap around the sensor or
the gate. In order to avoid problems, we recommend the installation of a filter,
such as the magnetic filter, type MFR.
If it is necessary to clean the sensor, the sensor can be rinsed with a suitable
liquid. Fiber parts or large particles can be carefully removed with tweezers, etc.
Ensure that the sensor is not damaged.
Work on the electronics can only be performed by the factory, or the warranty is
otherwise voided.
